Description

Technical Field

[0001] This invention relates to the field of filter technology, and in particular to a quick-installation, fixing, and airtight device for filters. Background Technology

[0002] Air filters are commonly used air quality treatment devices. They are consumables that need to be replaced regularly, and the airtightness and stability of the frame must also be ensured.

[0003] Currently, there are three main ways to install air filters:

[0004] 1. U-shaped groove side extraction is used, but this method is not applicable when there is insufficient side space or no side conditions.

[0005] 2. The L-shaped opening slot is used for front replacement, and spring clips are used to fix the four corners at an angle. However, this method has the problem of air leakage due to deformation in non-corner positions because there are no fixing clips, resulting in insufficient air tightness.

[0006] 3. Replacement can be done using an L-shaped slot or the front of the box, with fixing clips on all four sides. However, this method is inconvenient for replacement and the clips may occupy too much cross-section, making it unsuitable for spaces with a relatively small overall width. Summary of the Invention

[0007] The purpose of this invention is to solve the problems existing in the prior art by proposing a quick-installation, fixing, and airtight filter device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A quick-installation, fixing, and airtight device for a filter includes two support plates and a filter body, wherein the support plates are connected to the filter body via a fixing mechanism.

[0010] The fixing mechanism includes a connector, which consists of an L-shaped plate, an arc-shaped deformable plate, and an arched locking plate. The lower end of the L-shaped plate is fixedly connected to the upper end of the arc-shaped deformable plate, and the lower end of the arc-shaped deformable plate is fixedly connected to the upper end of the arched locking plate. The lower transverse surface of the L-shaped plate is connected to the filter body through the connecting mechanism. An elastic sealing cotton A is glued to the inner side wall of the L-shaped plate. The side wall of the arched locking plate is connected to the side wall of the support plate by a self-tapping screw. An elastic sealing cotton B is provided between the side wall of the arched locking plate and the support plate, and the self-tapping screw penetrates the side wall of the elastic sealing cotton B.

[0011] Preferably, the connecting mechanism includes a first Velcro fastener fixedly connected to the lower transverse surface of the L-shaped plate, and a second Velcro fastener that mates with the first Velcro fastener is fixedly connected to the upper end of the filter body. The connecting member is made of aluminum profile.

[0012] Preferably, the connecting mechanism includes multiple magnets fixedly connected to the upper end of the filter body, and the connecting parts are made of sheet metal.

[0013] Preferably, the magnet can be a single magnetic strip or a circular magnet block.

[0014] Preferably, there are two magnets, and an elastic sealing cotton C is fixedly connected to the upper end of the filter body between the two magnets, the height of the elastic sealing cotton C being greater than the height of the magnets.

[0015] Preferably, the arc of the arc deformation plate is 30-60°, the arc of the arched locking plate is 10-30°, and the elastic sealing cotton B covers the arc deformation plate and the arched locking plate.

[0016] Compared with existing technologies, the advantages of this invention are:

[0017] 1. The filter is easy to install and use.

[0018] 2. The corresponding sealing cotton is deformed into an inclined opening structure, which facilitates the insertion of the filter while achieving effective full-frame sealing.

[0019] 3. The external sealing cotton achieves external fixed sealing after locking.

[0020] 4. The adhesive parts are built-in and have an integrated structure, which avoids loss during replacement.

[0021] 5. The outer covering area occupies a very small portion of the overall ventilation area, greatly improving ventilation efficiency.

[0022] 6. It can be manufactured using aluminum profiles or sheet metal processing, which is low-cost and easy to promote on a large scale.

[0023] 7. The outer frame can be interconnected in parallel to achieve a large-area ventilation section for filtration. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] Reference Figure 1-4 A quick-installation, fixing, and airtight device for a filter includes two support plates 1 and a filter body 3. The support plates 1 are connected to the filter body 3 by a fixing mechanism.

[0036] The fixing mechanism includes a connector 2, which consists of an L-shaped plate 201, an arc-shaped deformable plate 202, and an arched locking plate 203. The lower end of the L-shaped plate 201 is fixedly connected to the upper end of the arc-shaped deformable plate 202, and the lower end of the arc-shaped deformable plate 202 is fixedly connected to the upper end of the arched locking plate 203. The lower transverse surface of the L-shaped plate 201 is connected to the filter body 3 through the connecting mechanism. An elastic sealing cotton A6 is glued to the inner side wall of the L-shaped plate 201. The side wall of the arched locking plate 203 is connected to the side wall of the support plate 1 through a self-tapping screw 8. An elastic sealing cotton B7 is provided between the side wall of the arched locking plate 203 and the support plate 1. The self-tapping screw 8 penetrates the side wall of the elastic sealing cotton B7.

[0037] The connecting mechanism includes a first Velcro 4 fixedly connected to the lower horizontal surface of the L-shaped plate 201, a second Velcro 5 that mates with the first Velcro 4 fixedly connected to the upper end of the filter body 3, and the connector 2 is made of aluminum profile.

[0038] The arc of the arc deformation plate 202 is 30-60°, the arc of the arched locking plate 203 is 10-30°, and the elastic sealing cotton B7 covers the arc deformation plate 202 and the arched locking plate 203.

[0039] It should be noted that in this invention, the two filters can be connected in parallel and interlocked. They only need to be installed on the side walls of the support plate to achieve a large-area ventilation section filtration.

[0040] In this embodiment, elastic sealing cotton B7 is covered at the curved deformation plate 202 and the arched locking plate 203. Then, self-tapping screws 8 are connected to the support plate 1 through the arched locking plate 203 and the elastic sealing cotton B7. When the self-tapping screws 8 are locked into the arched locking plate 203, the arched locking plate 203 gradually changes from an arched shape to a straight edge due to lateral tension. Simultaneously, the deformation tension causes the curved deformation plate 202 to deform clockwise, resulting in the elastic sealing cotton A6 tilting, further achieving filter sealing. Figure 4 As shown, the second Velcro 5 at the upper end of the filter body 3 is then attached to the first Velcro 4 on the lower surface of the L-shaped plate 201. Compared with the prior art, it has good airtightness and is easy to install and disassemble, and will not be unsuitable due to insufficient space.

[0041] Example 2

[0042] Reference Figure 5-6 The connecting mechanism includes multiple magnets 9 fixedly connected to the upper end of the filter body 3. The connector 2 is made of sheet metal, so that the magnets 9 can attract each other with the L-shaped plate 201.

[0043] Magnet 9 can be a single magnetic strip or a circular magnet block.

[0044] In this embodiment, the installation steps for the connector 2 are the same as in Embodiment 1. After installation, it is only necessary to tightly attract the multiple magnets 9 located at the upper end of the filter body 3 to the L-shaped plate 201 made of sheet metal.

[0045] Example 3

[0046] Reference Figure 7-8 There are two magnets 9, and the filter body 3 is fixedly connected to the upper end between the two magnets 9 with elastic sealing cotton C10. The height of the elastic sealing cotton C10 is greater than the height of the magnets 9, which further enhances the sealing and fixing effect.

[0047] In this embodiment, the installation steps for the connector 2 are the same as in Embodiment 1. After installation, it is only necessary to tightly attract the multiple magnets 9 located at the upper end of the filter body 3 to the L-shaped plate 201 made of sheet metal. At this time, the elastic sealing cotton C10 will be located between the filter body 3 and the L-shaped plate 201, which will increase the sealing and fixing effect of the filter body 3 after installation.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
